219 Quality and Wireless Infrastructure

219 Quality Without Wires Are you teaching quality today? That question started a young English teacher into a journey that led to the book Zen and the Art of Motorcycle Maintenance. But really, I wanted to talk about quality and wiring. I visited a prospect who was interested in a press control automation system. When I went into the plant to look at one of their presses, I saw a haphazard (and hazardous) wiring job on the control panel. I left as soon as I could. But wiring can be exceedingly expensive in many plants. Wireless became an attractive alternative. We had WirelessHart soon to be partly replaced by WiFi. Now, the latest cellular technology, 5G, when made into a private network coordinating with WiFi6, composes a powerful IoT and digital transformation communication system.
